Ok ok shh shh listen...
Nobody who owns a PS2 will buy a PSOne Ico unless maybe they add some neat stuff or something I dunno... Cuz Ico only costs like 30 bucks new... maybe 20-25 bucks used...
BUUUUUT....
There are still a ton of people who don't own a PS2, but own a PSOne! It's not like just cuz PS2 is out in the states and lots of people own it that eeeeveryone owns one.. sooo y'know it could still be a kinda good idea....
So basically, you're both wrong, now shut up
